Application filed April 24. 1917! Serial No. 164,220.

To all whom it may concern Be it known that I, JAMES E. MONTGQM- EKY ZL citizen of the UnitedStates-residm at Lancaster, in the county of Garrard an State of Kentucky, have invented new and useful Improvements in VihecLRims, of which the following is a specification.

This invention relates to carriages and wagons, and more especially to wheels; and the object of the same is to produce an'im proved sheet metal rim for a wheel adapted to receive a. resilient tire, such as the casing of an ordinary pneumatic tire;

l lssenti'all the rim is made in two telescopioshcet metal members", each having a flange toengage the side-of ortake over the bead along thelcasing otthe tire, with means for connecting the base portion or hands of these members where they overlie each other. Details are set forth in the following specification, and reference is made to the occompahyin'g' drawings wherein:

Figure 1. is aside elevation of this complete rim" ready for attachment to the folly of any ordinary wheel, but more espcclally intended to. be mounted on an automobile wheel, although I do not wish to be limited in this respect.

Fig. 2 is'an enlarged cross section on the line 2-.2 ofFig. 1. v 1

Fig. this an enlarged plan yiow taken from the inner f Fig. 1, and Fig. 4% is a perspective detail of the-latch.

Fig.6 is a sectional detail much like F 1g. 2, illustratinga slig'htmodification.

This implored .rim isv made of two telein Fig. 2, the outer member extends across the base oi the tire casing and the flanges 4 and 2 project radially outward alongside the tire which is not necessary to illustrate. lhese flanges may turn outward from each other at their outer edges so as to engage scopi'o jand' complementaryparts. The re llat sided tires. or they may hook inward toengage over heads on tires or tire cusings, arcording as the latter are made, and I. reserve the broadest latitude in this respect. As each part is made of sheet metal,

the flange can be rolled. or otherwise formed integral with the Hat band .or member, all at one operation. Said bands or members are of equal width as seen in the sectional news, and therefore when they are assem bled the outer member wholly underlies the base of the tire casing so as to leave. no craoks. I

which might pinch the. tube, member wholly underlies the outer room so as to reinforce it throughout its full widt and thereby permit both parts to be rhade of lighter material than would otherwise be the case. The free or unflanged edge of the outer member forms in ellect a shoulder whore it comes squarely into contact Wlth the inner face of the flange of the inner member and the inrfsh at a time when the frco edge of the latter is coincident with the flangcd'edg eof the o' uter member. At an appropriate point the outer member 1 is provided with a hole 5 throu h which is to project the nipple of-the air to e within the tire, and at a corresponding'point the inner member is provided with a transverse slot 6 leading from one edge of the member inward so that its inner end overlies the hole as seen in Fig. 3; and therefore when the parts are applied as described be low, the nipplewiltproject through the hole and the-inner end of. the slot as will be clearly understood without furtherillustration.

At several points around the rim, and at three points'as seen in Fig. 1 althoughI may employ these devices uta larger number of points. I provide latches 1 0 as seen in Fig. 4. Each has a relatively straight spring bod y 11 attached at one end by suitable means such as rivets 12'to the outer inemher 1 adjacent its flange 2 11s soon in Fig. 2, and the remote end of the body is bnt inward in a shoulder 13, thence, continued into a lip 14 provided with a longitudinal slot 15, andthe tip 16 of the lip preferably upturned as seen.- Touccommodate these several latches when the two members are sl i ppod togethor as doscri bod below, the inner member is provided atrorresponding points with recesses 17, each of a 'width to loosely the body up to the shoulder 13. Directly opposite the inner or closedend of the recess, the innermember carries a catch. 18, which, as seen in Fig. 2, is beveled on that face adjacent the recess and abrupt on its other or outer face, and through the tip or nose of this catch. may be formed a perforation as indicated at 19 in Fig.2. As suggested above,

.the body of the latch shown in Fig. 4 is preferably resilient so that it normally o'ccu- 1O pies the position In a slightly modified form of my invenseen in Fig. 2.

tion shown in Fig. 5, the catch 20 instead of being riveted at-12 to the inner member is ioted at 22 thereto and a leaf sprin 23 I a g is vmployed having. one end mounted fast by theresiliency of the on or secured to the pivot pin and the other end bearing against the body of the latch sm as to press its same as though it sprung toward the catch body in the type illustrated inv Fig. 2. In all other rcspectst 1e ,modified fornrshov'vn in Fig. 5 is essentially "the same as the form first described.

With this construction, the operation of 25 my device is as follows: When a tire is to be 40 through the hole 5 in the outer Q the now part; Of: the

30 flange 2,'a'nd placed on this rim, we will assume that the two parts thereof are separated. The casing, containing its tube, is now slipped around the outer member 1 and against its the flange and the side of the. casing are turned down and ground. The inner member 3 is now brought into position and slipped into the outer member, care bein taken that the several recesses l7 exactfy register with the lips'14t at the free ,ends of the several latches. This will be 'necessary because at this time'the slot 6 in. the inner member must of course the nipple which projects member, the partshaving thus been assembled. When now the inner member is borne downward, 'the beveled faces of the several catches 18 travel over the outturned tips 16 of the several latches, so that the latter are sprung if they are riveted at .12o'r deflected if they register with are pivoted at 22, and eventually the catches 18 snap into the slots 15 at a time when the flange upper edge of the outer mcm er 1, which it does when'the-..in' ner edges of the casing are pressed together to their proper extent. 'lhe rim is now placed on the felly and secured thereon by means formin no present invention, and either befoi-e or after this step the air'tube may be must remove parts, other'than as ip toward the catch, the.

laid upon the iii the lips 14 just 4 comes up a ainst said catches, and removable fastening inflated as usual. I mi ht say that for the sake of greater security havc shown in Fig. 3 howa pin 29 might be passed throu 1 each of the perforations 19 to revcnt t c possibility that any latch may ccome dis connected from its catch. This )iILCOIlld be a piece of wire, and if used t e operator the pin before he attempts to disconnect the two arts of this improved rim. I do not wishto be limited to the materials, proportions or exact details of hereinbefore set forth. but is claimed as new is:- 1. he herein described rim comprising an annular sheet metal member adapted to extend across'the base of a tire casing, a radial flange at one edge of said member, a. second sheet metal annular member of equal width with but sli htly smaller than the first and adapted to t telescopically into the same, a radial flange at one edge of the sec ond member adapted to abut against the free edge of the first, the inner member having at appropriate points transverse recesses em tending fiom its free edge inward, a catch on the inner face of this member opposite the inner end of each recess, and latches secured at corresponding points to the inner face of the outer member adjacent its flanged edge with their bodies adapted to lie in said recesses and their free ends deflecteddnto lips, er; 1b of the latter having a slot forengaging a catch.

2..The herein described rilh comprising einent'ary parts of sheet metal respectiv'ely including flat annular members of slightlydifferent size so that one will pass into the other but of equal width so that lhc outer will wholly overlie the inner when they are f asscmbled, and an outstanding flange at one edge of each member, the m ner member having transverse recesses at intervals, inwardly extending catches on this member opposite its recesses, each catch having a transverse perforation, latches attachcd at one end 'to'the inner face of the. outer member at intervals corresponding recesses with their bodies adaplcd to lie therein when the parts are assembled and their other ends deflected into lips, each having aslot for the reception .of one of de-,

.vicosthrough the perforations in the latter. In testimony whereof I aflix my signature? JAMES n. MONTGOMERY.
